PROBLEM TO BE SOLVED: To provide a parallel type information retrieving device and method for performing acceleration by dividing a document set and paralleling partial retrieval with a plurality of partial retrieval processors and also reducing storage capacity by storing only a subset of divided documents in each partial retrieval processor, a parallel type information retrieval program and a recording medium with the program recorded thereon. SOLUTION: A document set of a retrieval object is divided into a plurality of document subsets, each of a plurality of partial retrieval processors 100 provided corresponding to each of the plurality of divided document subsets parallelly retrieves each document subset with a retrieval key, a result integrating processor 150 collects a plurality of quasi-retrieval results being a plurality of partial retrieval results retrieved by the plurality of partial retrieval processors 100 from the respective partial retrieval processors 100, and the result integrating processor 150 retrieves a sum of sets of the collected quasi- retrieval results with the retrieval key.
